A really great hire is one who is successful in not just the role they were hired for, but also in progressive moves within the organization. Hiring managers should always be considering “where do we want this individual to develop from here” in the context of the larger organization’s needs, not just their own departmental or divisional needs.
This can often change the candidate specifications, demanding different criteria, such as a more diverse skill set, industry experience or even personal characteristics that are more likely to help promote success in the long-term opportunity, not just the current role.
This approach will help your managers keep succession in mind when hiring, and put your organization in a constant state of preparedness for inevitable change.
